Cable network operators

Network evolution

With video giving way to streaming content and enterprise services becoming more advanced, cable network and multiple-system operators (MSOs) are seeing their cable infrastructure pushed to the limit. Existing hybrid fiber-coaxial (HFC) architecture has inherent limitations. Deep fiber and the transition to pure-play digital transmission marks a turning point and opens up options for architectural improvement. The transition to distributed access architecture, with remote PHY devices replacing fiber nodes, brings a new set of synchronization requirements to cable access networks.

Getting digitized cable networks in sync

Oscilloquartz provides a complete synchronization portfolio for cost-efficient, manageable and precise timing of any device and application.

Accuracy to the edge

Timing delivery to the edge of the cable network was previously provided inherently by quadrature amplitude modulation (QAM) signals. As QAM signals in a distributed access architecture are created at the remote PHY device, this needs a supply of highly accurate timing information. That’s why a new mechanism for synchronization distribution must be introduced when migrating to such an architecture. GNSS-sourced grandmasters can be distributed in the network. This approach enables precise synchronization to be introduced in a much more flexible way.
